Earwigs: Identification, Prevention, and Control
Earwigs are fascinating yet often misunderstood insects that can be a source of concern for homeowners. At Arrest-A-Pest, we believe that understanding these creatures is the first step in effective pest management. In this comprehensive guide, we'll explore everything you need to know about earwigs, from their identification and biology to prevention tips and control methods.
Identification and Biology of Earwigs
Earwigs, scientifically known as Dermaptera, are easily recognizable insects with elongated bodies and distinct pincers (forceps) at the end of their abdomens. These nocturnal creatures have been the subject of many myths and misconceptions over the years. Let's delve into their physical characteristics, life cycle, and preferred habitats to better understand these intriguing insects.
Physical Characteristics
- Size: Earwigs typically range from 5 to 25 millimeters (0.2 to 1 inch) in length.
- Color: Most earwigs are reddish-brown to dark brown, with some species displaying patterns or markings.
- Body Structure: They have flattened, elongated bodies divided into three main sections: head, thorax, and abdomen.
- Antennae: Earwigs possess long, thin antennae that can be up to half the length of their body.
- Wings: Many species have two pairs of wings. The front pair are short, leathery wing covers (tegmina), while the hindwings are membranous and folded under the tegmina.
- Pincers (Forceps): Earwigs have a pair of pincers at the end of their abdomen. These pincers are curved in males and straighter in females.
One of the most common species in North America is the European earwig (Forficula auricularia). This species is often found in gardens and homes, making it a frequent subject of pest control efforts.
Life Cycle
Understanding the life cycle of earwigs is crucial for effective pest management. Earwigs undergo incomplete metamorphosis, passing through three stages: egg, nymph, and adult.
- Egg Stage: Female earwigs lay clusters of 20-80 smooth, oval, white or cream-colored eggs in the soil.
- Nymph Stage: Eggs hatch into nymphs after about 7 days. These young earwigs resemble small adults but lack wings and fully developed pincers.
- Adult Stage: Adult earwigs can live for up to a year. They are capable of flight but rarely do so, preferring to travel on foot.
Interestingly, earwigs display a rare behavior among insects: maternal care. The female will guard her eggs and even the newly hatched nymphs, protecting them from predators and grooming them.
Preferred Habitats
Earwigs thrive in moist, cool environments and are most active at night. They seek out dark, damp places during the day. Some common habitats include:
- Under rocks, logs, or mulch in gardens
- In leaf litter or compost piles
- Beneath tree bark or in rotting wood
- In basements, crawl spaces, or other damp areas of homes
- Around foundations of buildings, especially near water sources
While earwigs primarily live outdoors, they may enter homes seeking moisture or escaping extreme weather conditions.
Prevention Tips: Keeping Earwigs at Bay
Prevention is always better than cure when it comes to pest control. By taking proactive measures, you can significantly reduce the likelihood of an earwig infestation in your home or garden. Here are some effective prevention strategies:
Moisture Control
- Fix any leaky pipes, faucets, or air conditioning units.
- Ensure proper drainage around your home's foundation.
- Use dehumidifiers in basements or other damp areas of your home.
- Avoid overwatering your garden or lawn, especially near the house.
Seal Entry Points
- Inspect your home's exterior for gaps or cracks and seal them with caulk or another appropriate material.
- Ensure windows and doors fit tightly and use weather stripping if necessary.
- Check around utility lines and pipes entering your home and seal any gaps.
Maintain Your Yard
- Keep your lawn trimmed and remove leaf litter regularly.
- Store firewood away from your home and elevate it off the ground.
- Remove or relocate mulch, rocks, and other debris from around your home's foundation.
- Trim back vegetation that touches your house, as this can serve as a bridge for earwigs.
Use Proper Lighting
- Use sodium vapor lights or yellow bulbs for outdoor lighting, as these are less attractive to insects.
- Keep outdoor lights away from entry points when possible.
Natural Repellents
- Sprinkle diatomaceous earth around entry points and in garden beds.
- Use cedar mulch in your garden, as its strong scent may deter earwigs.
- Plant herbs like mint or garlic, which earwigs tend to avoid.
Regular Inspection and Cleaning
- Regularly inspect dark, damp areas of your home and yard.
- Clean gutters and downspouts to prevent moisture buildup.
- Vacuum or sweep floors, especially in basements and garages, to remove any earwigs that may have entered.
Treatment Methods: When to Call a Professional
While prevention is crucial, there may be times when earwig populations become problematic despite your best efforts. In these cases, professional pest control services can provide effective solutions. Here's what you need to know about earwig treatment and when to call in the experts.
DIY vs. Professional Treatment
For minor earwig issues, DIY methods can be effective. These might include:
- Using sticky traps in areas where earwigs are frequently seen
- Applying food-grade diatomaceous earth around entry points
- Setting up oil pit traps (shallow containers filled with vegetable oil and soy sauce) in the garden
However, these methods may not be sufficient for larger infestations or persistent problems. Professional pest control services have access to more potent and targeted treatments.
When to Call a Professional
Consider contacting a licensed pest control professional like Arrest-A-Pest if:
- You're seeing large numbers of earwigs in or around your home

- You want a comprehensive pest management plan that addresses earwigs and other potential pests

Pest Behavior and Risks: Understanding the Impact of Earwigs
While earwigs are generally considered more of a nuisance than a serious threat, understanding their behavior and potential risks can help homeowners make informed decisions about pest management.
Earwig Behavior
Earwigs exhibit several behaviors that can lead to infestations:
- Nocturnal Activity: Earwigs are most active at night, hiding in dark, damp places during the day.
- Moisture-Seeking: They are attracted to damp environments, which is why they're often found in bathrooms, basements, and around leaky pipes.
- Omnivorous Diet: Earwigs feed on a variety of materials, including plants, other insects, and decaying organic matter.
- Aggregation: Earwigs release pheromones that attract others of their species, potentially leading to large gatherings.
- Seasonal Movement: They may enter homes in large numbers during extreme weather conditions, seeking shelter from heat, cold, or excessive rain.
Potential Risks and Concerns
While earwigs are generally harmless to humans, they can pose some risks:
- Garden Damage: Large populations of earwigs can damage flowers, vegetables, and soft fruits in your garden.
- Nuisance Factor: The presence of earwigs in homes can be distressing for many people, even if they don't pose a direct threat.
- Rare Pinching: While uncommon, earwigs may pinch if handled roughly, which can be startling but rarely causes injury.
- Indirect Health Concerns: Like many pests, earwigs can potentially carry bacteria on their bodies, though they are not known to transmit diseases to humans.
It's important to note that many common beliefs about earwigs are myths. For instance, they do not crawl into people's ears to lay eggs or bore into the brain.
